Application June 26, 1951, Serial No. 233,613

12 Claims. (Cl. 26-2) The present invention relates to a pile processing machine and procedures and it particularly relates to a machine and procedure for enhancing and improving the quality and texture of a pile, whether woven or otherwise applied to a textile material.

Although the present invention will be particularly directed to the processing and treatment of pile fabrics, it is to be understood that it has a wide application to the processing and treatment of various types of Woven, knitted or felted fabrics upon which it is desired to obtain soft, velvety or nap surface effects by straightening the projecting fibres.

It is among the objects of the present invention to provide a novel machine and procedure for surfacing textile fabrics, particularly those having pile and similar surfaces, which will give assurance that such pile Will be enhanced and modified so as to have an improved hand without damaging or weakening the fabric and at low cost with a minimum of labor.

Another object is to provide a novel pile fabric finishing machine and process for enhancing and refurbishing the pile, which will give the pile a rich, lustrous and noncrushable efiect as a result of relatively short treatment without damaging the fabric or the pile, and without decreasing its normal wear or durability.

Still further objects, and advantages, will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects, it has been found most desirable to provide a relativelylong cylinder having a plurality of grooves therein curved steel edge faces for combing the pile or processing the same or for similar surfacing of the fabric.

The cylinder should usually be heated to an elevated temperature which, however, will not damage the pile during the time of contact therewith and desirably the grooves on the cylinder with their relatively sharp ironing edges or faces are so spaced that they will assure uniform treatment of the entire pile without streaking or otherwise giving excess or under-treatment to any portions of the fabric.

In the desired construction, the rotating heated cylinder is mounted in a fixed position while the fabric or material being treated is elevated against the cylinder and caused to undergo the ironing, combing, beating or rubbing treatment under a substantial amount of controlled pressure.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Fig.1 is a front elevational view of a pile fabric processing machine according to the present invention, partly broken away so as to enable a lessening in width of the machine.

Fig. 2 is a transverse, vertical sectional view upon the line 2--2 of Fig. 1

Fig. 3 is a vertical transverse sectional view similar to Fig. 2 of an alternative embodiment.

Fig. 4 is a diagrammatic plan view of an alternative ironing cylinder construction which may be substituted for that shown in Figs. 1 to 3. V

Fig. 5 is a diagrammatic plan view of still another cylinder construction which may be substituted for that shown in Figs. 1 to 3.

Referring to Figs. 1 and 2, there is shown a frame A provided with a table B, an upwardly and downwardly reciprocable support arrangement C for the fabric or other article being treated, an ironing roller arrangement D and an exhaust arrangement E.

The machine frame has the side members which have the feet 11, the legs 12 and the top support structure or table support structure 13, as shown in Fig. 2.

Extending upwardly and inwardly from the structures 14 are the oblique beams 15 which support the structure 16. The motor structure 17 has the support feet 18 and it drives the pulley 19 by the shaft 20.

To the rear of the frame A are positioned the structures 21 having the forwardly projecting ears '22 with the pivotal connections 23. The pivotal connections 23 connect to the downwardly depending elements 24 of the pneumatic or hydraulic cylinder members 25. The cylinder members 25 receive the reciprocable pistons or tubular elements 26.

The pistons or reciprocable elements 26 have the upwardly extending actuating members 27 which are of clevis shape and have a pivotal connection at 28to the U-shaped bars or brackets 29. The brackets 29 are pivotally mounted at 30 upon the bearing members 31, which bearing members in turn are mounted by the bolts 32 upon the structural elements 33 and 34.

Connecting the forward ends 35 of the arms or brackets 29 is the pipe or tube 36.

On the tube 36 by the rivet or bolts37 are mounted the canvas or wire mesh support member 38 and the felt or other soft covering element 39. The rib 40 attached to the tubular member 36 and extending between the [brackets 29 supports and reinforces the tube 36, between the brackets 29.

The felt blanket as shown in Fig. 2 terminates at but the canvas support 38 extends as indicated at 51 over the fixed tubular member 52 until it is engaged at 53 by the clevis members 54 at the upper ends of the rods 55. The rods extend through and are supported by the webs 56 on the brackets 57. At the lower end of the rods there are provided washers 58 and the nuts 59, which washers 58 bear against the springs 60 which at their other ends bear against the webs 56.

The tubular member 52 is supported at its ends by the rods 61 on the side frame 10.

The ironing roller D has a cast-iron or casts-tee} outer shell upon which there are a series of curved grooves 76, 77, 78, 79, 80, 81, 82 and 83 so arranged as to cover the entire surface of the fabric being treated.

As best shown in Fig. 2, each groove has a shallow or approach 84 with a direction of rotation as indicated by the arrow 85 and a relatively deep rear face 83 which has a hard metal, replaceable steel blade 87 which does the actual combing or processing of the fibres. 4
